In the article titled “Distribution and Bioaccumulation of Perfluoroalkyl Acids in Xiamen Coastal Waters” [1], there is an error in the first sentence of the Abstract section, where “harmless” should be corrected to “harmful” as follows: “Since perfluoroalkyl acids (PFAs) are widely used and harmless to organisms, they have attracted great attention in recent years” to “Since perfluoroalkyl acids (PFAs) are widely used and harmful to organisms, they have attracted great attention in recent years.”
